Laputa update wont read older books

I downloaded Laputa eBook reader a while back, and have already downloaded about a dozen books through it. Now the update for Laputa has come through I reads my library as empty, and there is no way to manually add the books already on my SD card.
Anyone know of a fix?
And failing that, anyone know of a good reader that actually works?

I have had the Laputa app for about a month now and was really loving it, but today after I did the update it is completely gone! I can't even find it in the android marketplace.....does anyone have any suggestions? I was right in the middle of a book series and now it's completely useless without the Laputa app.

Could someone share the 2.2.0 version before they delete it? I had it working fine (needed to re-download all my books, and had to do it over wireless - didn't work over 3g), but I updated to 2.2.1 this morning and it won't even start anymore. I tried to do a clean reinstall but in the 5 minutes between my downloading it the first time and trying the clean install it has been removed from the market (or the market is a bit broken, one or the other).
